in the like term you can add directly and make it single fraction and in unlike term you have to take LCM of denominator .

Answer:
The second term of the binomial factor should be 3c instead of 3.
Step-by-step explanation:
Distributive property:
a*b + a*c = a*(b +c)
3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)
Since A‘(-1,1) is on the line y=-x, reflecting it about the line doesn't change its coordinate, so A's coordinate is (-1,1). Reflecting B'(-2,1) about y=-x switches both the sign and the number of x and y, so B=(-1,2), and C'(-1,0) becomes C(0,1). Drawing out the graph with the points and the line helps.
-6x-7+8=19 and then add your like terms so it’s -6x+1=19 and then subtract one on both sides so it’s -6x=18 so x=-3
